Deed of Assignment vs. Deed of Lease vs. Deed of Sublease: Key Differences Explained

Deed of Assignment vs. Deed of Lease vs. Deed of Sublease: Key Differences Explained

Introduction

In Nigerian urban property practice—especially in Lagos and adjoining corridors—three instruments dominate most sophisticated transactions: the Deed of Assignment, the Deed of Lease, and the Deed of Sublease. They are cousins, not twins. Each conveys a different legal estate, attracts different consents and risk profiles, and supports different commercial outcomes. Confusing them is expensive: you could pay for “ownership” but receive only a time-bound tenancy; or you might sign a “lease” where your real need is to acquire the residue of a statutory right of occupancy.

This counsel-grade guide explains—in practical, bank-ready language—the core distinctions, use-cases, drafting essentials, consent/stamping/registration pathways, and red-flag traps. If you are buying, selling, investing, lending, or developing, use this as your operational playbook.

Doctrine: Never pay for land—pay for the correct estate, correctly perfected.

Part I — Plain-English Definitions

• Deed of Assignment
  Transfers (assigns) to the buyer the assignor’s entire interest in the property—i.e., the residue of the statutory right of occupancy or other registrable estate. It is a sale of the proprietary interest itself (not mere possession). Typically perpetual in effect, subject to statutory tenure and conditions in the root title.

• Deed of Lease
  Grants the right to exclusive possession for a term certain (e.g., 5, 10, 20, 99 years) in exchange for rent/premium. The freehold/statutory root remains with the lessor. It is time-bound; at expiry, possession reverts to the lessor unless renewed.

• Deed of Sublease
  A lease granted by a lessee (not the freeholder) to a sublessee out of the lessee’s term. It cannot exceed or outlast the head-lease; it is derivative and subject to the covenants in the superior lease. Frequently requires the lessor’s consent (as a matter of contract) and, where the head interest is a statutory right of occupancy, Governor’s Consent to the sublease as a registrable instrument.

Part II — The Legal Estate You Actually Get

Part III — When Each Instrument Is Commercially Sensible

• Use a Deed of Assignment when:

  • You want marketable ownership (to develop, refinance, or resell).

  • You are buying an already titled plot/house from a C of O holder or assignee.

  • You need bank collateral (lenders prefer consented, registered assignments).

• Use a Deed of Lease when:

  • You want long-term control but not the capital outlay of a full purchase.

  • You’re structuring build-to-rent or ground leases for income projects.

  • Your counterparty cannot (or will not) sell the reversion but will grant a term.

• Use a Deed of Sublease when:

  • You hold a lease and wish to monetize surplus space or re-tenant a site.

  • The estate strategy requires flexibility under a head-lease (e.g., malls, office floors).

  • You’re bridging occupancy while a larger transaction (assignment or head-lease renewal) is engineered.

Part IV — Consents, Stamping & Registration (Perfection Map)

Golden rule: In Lagos and similar jurisdictions, the perfection triad is
(1) Stamp Duties → (2) Governor’s Consent (where applicable) → (3) Registration.

• Deed of Assignment:

  • Consent: Governor’s Consent required (derivative transfer of a statutory right).

  • Stamp: Ad valorem on consideration.

  • Register: At Lagos State Lands Registry; obtain registration particulars.

• Deed of Lease:

  • Consent: Where the reversion is a statutory right, practice is to obtain Governor’s Consent to the lease (registrable interest).

  • Stamp: Duty on rent/premium and term.

  • Register: Yes—especially for long terms; registration secures priority and searchability.

• Deed of Sublease:

  • Consent: Often two layers—(i) lessor’s contractual consent under the head-lease; and (ii) Governor’s Consent (derivative, registrable instrument).

  • Stamp: On rent/premium.

  • Register: Yes; otherwise, priority and enforceability suffer.

Bankability test: If a prudent bank would not lend on the file today, you are not done today.

Part V — Core Drafting Architecture (What Must Be Inside)

A. Deed of Assignment — essentials

• Recitals: Root of title (C of O/Allocation/Excision) and clean chain down to assignor.

• Operative words: “assign, transfer and convey the entire estate and interest…”

• Consideration: Amount; escrow acknowledgment if used.

• Covenants for title: Right to assign; freedom from undisclosed encumbrances; further assurances.

• Habendum: “To hold unto the Assignee for the residue of the term…”

• Schedule/Plan: Registered survey (hard + soft CAD).

• Execution: Proper individual/corporate blocks; witnesses; seals.

B. Deed of Lease — essentials

• Term & commencement; rent, review mechanics, and premium (if any).

• User clause (permitted use); alienation (assignment/underletting) restrictions.

• Repairs & insurance; service charge regime (if multi-let/estate).

• Quiet enjoyment; lessor’s covenants (possession, title).

• Re-entry/termination; forfeiture and relief mechanics.

• Yielding up and reinstatement; options (renewal, expansion).

• Schedules: Plans, car parks, shared areas, “fit-out” obligations.

C. Deed of Sublease — essentials

• Compliance with head-lease; sublease subject to and with the benefit of superior covenants.

• Term within head-lease term; rent and service charge alignment.

• Required consents (landlord/head-lessor) and direct agreements where needed.

• Step-in and assignment/underletting provisions consistent with head-lease.

• Break rights harmonized with head-lease events.

• Disclosure: Deliver certified copy of head-lease to sublessee.

Part VI — Risk & Remedies Matrix

Part VII — Commercial Scenarios (What to Choose & Why)

1. You’re buying a plot/house to hold or develop: Assignment (ownership-level control; best for finance and resale).

2. You want long-term control of a site near a corridor (e.g., infrastructure) but not outright purchase: Long Lease (ground lease).

3. You have excess retail/office floorspace under a head-lease: Sublease (monetized space; preserve head obligations).

4. You’re a developer selling units in a built-to-rent scheme: Head-lease from landowner + underleases to tenants/investors, carefully crafted to protect the capital stack.

5. You’re bridging occupancy pending approvals or funding: Short lease/sublease with clear break rights, while an eventual assignment is engineered.

Part VIII — Perfection Workflow (Practical, Lagos-Ready)

1. Due diligence: Lands Registry search + CTCs; OSG charting with soft coordinates; court/CAC checks.

2. Contract architecture: Escrow, Conditions Precedent (Consent, OSG clean, discharge, CTCs, originals), long-stop, retention.

3. Drafting: Correct instrument (assignment/lease/sublease), with schedules and plan.

4. Stamp Duties: Within statutory window (plan ≤30 days from execution).

5. Governor’s Consent: File clean pack; track queries; maintain name/description hygiene.

6. Registration: Obtain registration particulars; order CTCs for the finance file.

7. Aftercare: Insurance, estate onboarding, tax diaries, digital vault of notarized scans; originals in fire-safe.

Part IX — Clauses You Can Adapt (Illustrative)

Consent as Condition Precedent (for any instrument):

“Completion is conditional upon issuance of Governor’s Consent to the [Deed of Assignment/Lease/Sublease] in favour of [Buyer/Lessee/Sublessee] and delivery of evidence of stamping and registration particulars from the Lagos State Lands Registry.”

OSG & Planning Cleanliness:

“Completion is conditional upon an OSG charting report confirming the Property lies outside acquisition/committed areas, ROW/pipelines/coastal or drainage setbacks and without overlap; and upon documentary evidence of applicable planning/building approvals.”

Head-Lease Compliance (Sublease):

“This Sublease is subject to and with the benefit of the covenants and conditions of the Head-Lease, a certified copy whereof is annexed hereto; the Sublessee shall not do or omit any act which would put the Lessee in breach of the Head-Lease.”

Retention/Holdback:

“₦… (or …%) of the price/premium shall be retained in escrow until evidence of Consent endorsement and registration particulars is delivered and (where applicable) discharge of any registered charge is filed.”

FAQs (Concise Counsel)

Q: Can I convert a lease into an assignment later?
A: Only by separate assignment of the reversion or restructuring; a lease itself does not morph into ownership.

Q: Does registration cure lack of Governor’s Consent?
A: No. You need Consent (where applicable) and registration, both duly stamped.

Q: Can a sublease outlast the head-lease?
A: No. It is derivative; when the head-lease ends, the sublease typically falls with it.

Q: Which is best for financing—assignment or lease?
A: Consented, registered assignments are generally superior collateral. Long leases can work if consented, registered, and lender-friendly.

Conclusion

The instrument you choose dictates your power over the land, your ability to finance, and your exit. Assignment buys the estate; Lease buys time and control; Sublease buys a slice of someone else’s time—each must be perfectly engineered with Consent → Stamp → Register, OSG-clean boundaries, and disciplined contracting. That is how institutions transact—and how you protect capital.
